Emerging Technologies Enabling the Transition Toward a Sustainable and Circular Economy : The 4R Sustainability Framework

Abstract

A Circular Economy (CE) is an emerging economic model, restorative and regenerative by both intention and design. The CE evolves in a repetitive cycle, where waste is returned back into the of a new product by recycling and reusing materials. Thus, CE represents a sustainable and productive economy model that is financially, economically, and socially feasible. It is increasingly regarded as an acceptable and desirable solution to achieving prosperity whilst acknowledging ecological and social boundaries. Opposed to the unsustainable Linear Economy, it draws on complexity and systems thinking by imitating nature that does not produce any waste. However, the implementation of CE in industry is slow paced, mainly due to barriers caused by complex sustainability transitions and innovations needed to cover a systemic and systems thinking approach. In the last few years, the concept of a CE and the transition from a linear, take-make-waste system to a cyclic system that reuses, remanufactures, and recycles materials, have gained increased importance, and have attracted considerable attention from both scholars and practitioners. Research that examines the role of emerging technologies in supporting this transition is therefore imperative. The CE has also become a key policy objective due to increased frequency of natural disasters which have been caused by human activity and social pressure on policymakers and governments to introduce measures in order to ensure sustainability, bio-based products and sustainable processing. This study discusses the concept of the CE as well as the transition from a Linear to a closed-loop Circular Economy based on resource regeneration and ecosystem restoration. It unfolds the role and importance of emerging technologies related to Industry 4.0 and Industry 5.0 in this transition by analyzing their adoption and implementation in the context of the CE. The key benefits of transformational change include increased engagement, improved performance, and higher levels of creativity and innovation. The ultimate and implicit aim of this paper is to increase awareness of the required actions ideally from every single individual on earth. Through increasing understanding of the fact that the use of emerging technologies is not a magic wand for addressing the ecological challenges but a tool for supporting the transition to a cleaner environment. In order to obtain an authentic and genuine transition, a fundamental social and cultural shift needs to pave the way.
